Over the last ten years, robustness of schemes has raised an increasing interest among the CFD community. The objective of this article is to solve the quasi-one-dimensional compressible flow inside a “Shubin nozzle” and to investigate Bean-Warming and flux vector splitting methods for numerical solution of compressible flows. Two different conditions have been considered: first, there is a sup...

For the improvement the postharvest longevity of cut alstroemeria (Alstroemeria hybrida L.), a factorial experiment was carried out based on RCD with 2 factors of stem end splitting at two levels (5 cm splitting and without splitting) and ethanol at five levels (0, 1, 2, 4 and 6%), 10 treatments, 3 replications and 30 plots. In this experiment, the estimated traits included vase life, water abs...

Developing low-cost oxygen evolution reaction (OER) catalysts with high efficiency and understanding the underlying mechanism are critical for electrochemical conversion technologies. Here, an anodized Prussian blue analogue (PBA) containing Ni Co is reported as a promising OER electrocatalyst in alkaline media. Detailed post-mortem characterizations indicate transformation from PBA to Ni(OH)2 ...

Context. W75N(B) is a massive star-forming region that contains three radio continuum sources (VLA 1, VLA 2, and VLA 3), which are thought to be three massive young stellar objects at three different evolutionary stages. VLA 1 is the most evolved and VLA 2 the least evolved source. The 22 GHz H2O masers associated with VLA 1 and VLA 2 have been mapped at several epochs over eight years. While t...

curls and curves of a shell interweave its various strain modes and link them together. this interactional behavior has yet frustrated all attempts for the construction of shell templates, which needs for an individual element test in traditional approaches. such a test fails to work for shell elements and must be reconstructed. in this paper, it is tried to study shell interactional behavior a...

One of the most fundamental properties characterizing the propagation of a nucleon in nuclear medium is its effective mass[1, 2, 3]. The latter describes to leading order the effects related to the non-locality of the underlying nuclear effective interactions and the Pauli exchange effects in many-fermion systems. In neutron-rich matter, an interesting new question arises as to whether the effe...

Global Krylov subspace methods are the most efficient and robust methods to solve generalized coupled Sylvester matrix equation. In this paper, we propose the nested splitting conjugate gradient process for solving this equation. This method has inner and outer iterations, which employs the generalized conjugate gradient method as an inner iteration to approximate each outer iterate, while each...
